1, can't be eaten with cold food. Black herring is cold, so it is best to avoid eating with some cold foods, such as spinach, cucumber and other vegetables. It is not advisable to drink some iced drinks such as soda, ice water and ice cream immediately after meals, and pay attention to eating less or not eating cold fruits such as watermelons and pears to avoid physical discomfort.
2. Don't eat beer or red wine. Eating herring and drinking a lot of beer will produce too much uric acid and lead to gout. Excessive uric acid will be deposited in joints or soft tissues, which will cause inflammation of joints and soft tissues.
